Answer:
The height of the roof is 534.8 feet.
Step-by-step explanation:
Let h be the height of the roof.
We know the formula

Since, the stone is dropped from the edge of the roof hence, the initial velocity should be zero. Thus, u = 0

Now, we have
v = -185 feet per second
g = 32 feet per square second
On substituting these values, we get

The height of the roof is 534.8 feet.
